Nice find.

Not to sound like a nerd, but here is a way to calculate the capacity of any pot in gallons.
Average radius squared * depth * Pi / 231 = capacity in gallons.
Using the #10 on Rat's Chart as an example:
12.25 + 10.75 = 23 / 2 = 11.5 (avg. diameter)
11.5 / 2 = 5.75 (avg. radius)
5.75 * 5.75 * 4.875 * 3.1418 = 506.3943 (capacity in cubic inches)
506.3943 / 231 = 2.1922 (capacity in liquid gallons)
Keep in mind that this is the max capacity of the pot to the rim.

Awesome!
Do you have a formula for round-bottom pots (kettles)?

Take the inside diameter at the top of the pot and another measurement about half way down the inside of the pot and average the two.
If you have a flat lid, slide it half way back and measure from the center of bottom on the pot to the underside of the lid to get the depth.

Now, see I thought you would try to measure the inside diameter where the bottom just starts to curve. Calculate the volume of a sphere that diameter and half it. That's the volume of the curved part.
Then measure from where the curve starts up to the rim and use that length and the diameter to calculate the volume of that cylinder.
Add the 2 together for the total capacity.

I don't see why that wouldn't work.

Well, now that I look at some images of pots, the rounded part isn't always a full half-sphere, so the calculation would be a bit more involved. Some are even more complicated because the curve isn't circular.
Best bet, if you have the pot, is to add water from gallon jugs and count how much water fits in the pot. Then you know for sure.

Well now we arrive at the most common sense solution.

I was going to say something, but after reading all that I got a headache.
Just buy a # 12 and be done with it.
My # 12 is also my go to Gumbo pot.
